Chemical structure of Rg3 and study design. a Structure of Rg3. b After a 5-day adaption period, the mice were given Rg3GE (50 or 100 mg/kg, p.o.) or RGE (100 mg/kg, p.o.) for a total of 14 days. Beginning on day 9, scopolamine (1 mg/kg, i.p.) was also administered for 6 days, and the Morris water maze test was used to assess behavior during this period (days 9–14). On day 14, each mouse was sacrificed, and the hippocampus was removed for the analysis of acetylcholinesterase activity and NF-κB activation. c Groups and treatment
